Hiya, my build is the same as yours :)There are many threads here about PCs sleeping after 2 minutes e.g.
Windows 10 sleeps after 3 minutes, no matter what. Solved - Windows 10 Forums
Goes to sleep after 2 minutes??? - Windows 10 Forums
Computer goes to sleep 2 minutes after last command Solved - Windows 10 Forums
Windows 10 64 Bit Monitor display turns off after 2 minutes! Solved - Windows 10 Forums
It seems most of these are older threads, and yours is, as @f14tomcat said, apparently an older build (2 major builds back).
As he asked, please
press Windows key + R, type winver and post the result.
E.g. mine is 15063.674.
Also please post a screenshot of your Update History so we can see if Windows update is functioning - unless you know you've disabled it?
